Unit 13 ThinkUp Concept Practice (water cycle)

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What role does the sun play in the water cycle?

Back

The sun provides energy that heats the ocean, causing water to evaporate and form clouds.

Front

Define evaporation in the context of the water cycle.

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

How does gravity affect the water cycle?

Back

Gravity pulls water down from clouds as precipitation and helps water flow in rivers and streams.

Front

What is the importance of the ocean in the water cycle?

Back

The ocean is a major source of water for evaporation, contributing to cloud formation and precipitation.

Front

What safety precaution should students take when investigating evaporation outdoors?

Back

Students should not look directly at the sun to protect their eyes.

Front

How does temperature influence the water cycle?

Back

Higher temperatures increase evaporation rates, while lower temperatures can lead to condensation and precipitation.

Front

What is the relationship between evaporation and cloud formation?

Back

Evaporation adds water vapor to the atmosphere, which cools and condenses to form clouds.
